P2P-based massive multi-player online games (MMOGs) use information dissemination overlays for exchanging game control and position updates among players or peers. Although these overlays are massively scalable and accommodate highly dynamic peers, yet they are prune to deliberate perturbations or cheating by adversaries. Cheating in MMOGs lead to poor quality of gaming services, unavailability...

Efficient route maintenance in DHTs is still an area of very active research due to its complexity and multitude of aspects to be considered. In this paper we propose novel correctionon-failure (CoF) and correction-on-use (CoU) approaches that support route maintenance more efficiently than existing methods even under highly dynamical network conditions. In contrast to previous work which addre...

Peer-to-peer networking enjoys euphoric support and fierce resistance simultaneously, and for the same reasons. It presents a model where decentralization and lack of structure, hierarchy and control are promoted. Although significant research is carried out to tackle individual issues arising from that paradigm, there has been no obvious approach for evening out differences on a more general b...

Proxy-based multicast is an approach to implementing the multicast function with proxy servers, which has many advantages compared to the IP multicast. When proxy locations are predetermined, many routing algorithms can be used to build a multicast overlay network. On the other hand, the problem of where to place proxies has not been extensively studied yet. A study on the placement problem for...

Laplacian-based approximate consensus algorithms are an important and frequently used building block in many distributed applications, including formation control, sensor fusion, and synchronization. These algorithms, however, converge extremely slowly on networks that are more than a few hops in diameter and where values are spatially correlated. This paper presents a new algorithm, Power Law ...

This document describes a Layer3 Virtual Private Network (L3VPN)based subnet extension solution referred to as Virtual Subnet, which can be used for building Layer3 network virtualization overlays within and/or across data centers.

Museums and researchers both have a need to display and interact with high-resolution data. There is great interest in using multi-touch tables, most of which are projector-based. However LCD-displays are becoming an attractive alternative to projectors because of their low cost of maintenance and image clarity. While touch screen overlays have been available for LCD panels for some time, these...

Distributed Hash Tables (DHTs) may suffer from a high lookup latency due to the issue of topology mismatching between the overlay and the physical underlying network. To handle this problem, recently, some researchers use network coordinates (NCs) to construct topology-aware DHTs(e.g. Canary). However, these proposed DHTs still have room to be improved due to the inaccuracy of NCs. To construct...

Despite suffering from inefficiency and flexibility limitations, the filter-based routing (FBR) algorithm is widely used in content-based publish/subscribe (pub/sub) systems. To address these limitations, we propose a dynamic destination-based routing algorithm called D-DBR, which decomposes pub/sub into two independent parts: Content-based matching and destinationbased multicasting. D-DBR exhi...

Considerable research effort has recently been devoted to the design of structured peer-to-peer overlays, a term we use to encompass Content-Addressable Networks (CANs), Distributed Hash Tables (DHTs), and Decentralized Object Location and Routing networks (DOLRs). These systems share the property that they consistently map a large space of identifiers to a set of nodes in a network, and while ...
